The Marvel Rivals Unmount Blocker and the ban reports

RIVALSFPS.GG October 14, 2026 Updated November 13, 2026 5 min read

The Unmount Blocker is a plugin for Marvel Rivals, a single .asi file, that stops the game from closing mods after it starts. Since mid-October 2026, players running it have been reporting in-game warnings and bans, and the mod's own download page now carries a ban warning in its title. If you have it installed, remove it. RIVALSFPS.GG 5.3.0 checks for it and offers to remove it before you launch the game.

What the Unmount Blocker does

Since a September 2026 update, Marvel Rivals closes, or unmounts, mods packaged as plain .pak files shortly after the game starts. Anything the game reads from those mods later stops working. Hero voice mods were hit hardest: a hero's voice lines load when that hero does, by which time the mod has already been closed.

The Unmount Blocker is loaded into the game by an ASI loader, the same way the Signature Bypass is, and patches the game's unmount routine in memory so those .pak files stay open. That is a change to the running game itself, not to files the game reads.

Why it is a ban risk

Players running it have reported in-game warnings and bans, and its download page now warns about bans. Patching the game while it runs is exactly the kind of client modification anti-cheat software looks for. Nobody outside NetEase can say exactly what their detection checks, so this page is not a promise either way. Removing the Unmount Blocker is the safe call, and you do not lose anything RIVALSFPS.GG does by doing it. NetEase's rules on modding in general are covered in Are Marvel Rivals mods bannable?.

How to check whether you have it

The file is MarvelRivalsUnmountBlocker.asi. Mod managers and manual installs put it here, inside your Marvel Rivals folder:

MarvelGame\Marvel\Binaries\Win64\plugins\, the usual place
MarvelGame\Marvel\Binaries\Win64\scripts\, which some ASI loaders also read
MarvelGame\Marvel\Binaries\Win64\ itself

A renamed copy loads just the same, so a different file name does not mean you are clear. RIVALSFPS.GG recognizes it by its contents as well as its name.

Remove it with RIVALSFPS.GG

RIVALSFPS.GG 5.3.0 looks for the Unmount Blocker in all three places, under any name:

When the app starts. A "Remove the Unmount Blocker?" prompt names the file it found. Remove it takes it out; Keep it leaves it.
When you press Launch. If it is still there, the app asks again before the game starts. Remove and launch removes it and starts the game in one click. Launch anyway starts the game with it, and closing the prompt cancels the launch.

Removing it moves the file into Binaries\Win64\RivalsFPS-Quarantine, where the game no longer loads it. Nothing is deleted, and the app checks the file is gone before it says so or starts the game. If the folder needs administrator rights, Windows asks once.

Remove it by hand

Close Marvel Rivals. A running game keeps the file locked.
Open MarvelGame\Marvel\Binaries\Win64\plugins in your game folder.
Delete MarvelRivalsUnmountBlocker.asi, or move it out of the game folder.
Leave dsound.dll and MarvelRivalsUTOCSignatureBypass.asi alone if you use the Signature Bypass. Those are not the Unmount Blocker.

Getting voice mods back without it

Most people installed the Unmount Blocker to get voice mods working again. RIVALSFPS.GG 5.3.0 does that a different way. Update my mods converts each voice mod so its lines play from sound files the game loads at startup, which the game never unmounts. Open the Mod Manager, look for sound mods marked Outdated, and click Fix. The whole process is in Marvel Rivals voice mods not working.

Common questions

Does RIVALSFPS.GG need the Unmount Blocker?

No. Nothing RIVALSFPS.GG installs depends on it. Its graphic packs and the mods its Fix button repackages load as IoStore containers, which the game keeps open, and sound mods play from sound files the game loads when it starts.

Is the Unmount Blocker the same thing as the Signature Bypass?

No. Both are plugins loaded by an ASI loader, but they do different jobs. The Signature Bypass lets the game load mods at all. The Unmount Blocker patches the running game so it stops closing old-style .pak mods after it starts. Removing the Unmount Blocker leaves the Signature Bypass and your mods where they are.

Will removing the Unmount Blocker break my mods?

Skins, graphic packs and other mods packaged as .utoc/.ucas/.pak sets keep working. What stops are old-style .pak mods whose files the game reads after startup, most often hero voice mods. Since RIVALSFPS.GG 5.3.0, Update my mods converts voice mods so they play without it.

Where does RIVALSFPS.GG put the file when it removes it?

Into Binaries\Win64\RivalsFPS-Quarantine in the game folder. It is moved, not deleted, and the game no longer loads it from there. A quarantine.json beside it records what was moved and from where.

Does the app remove it without asking?

No. It asks when the app starts and again when you press Launch. Keep it at startup or Launch anyway on the Launch prompt leaves the file where it is.
